Intel Core i3-7130U vs Intel Core i5-7440HQ
Intel Core i3-7130U► remove from comparison
The Intel Core i3-7100U is a dual-core processor of the Kaby-Lake architecture. It offers two CPU cores clocked at 2.7 GHz (without Turbo Boost) and integrates HyperThreading to work with up to 4 threads at once. The architectural differences are rather small compared to the Skylake generation, therefore the performance per MHz should be very similar. The SoC includes a dual channel DDR4 memory controller and Intel HD Graphics 620 graphics card (clocked at 300 - 1000 MHz). It is manufactured in an improved 14nm FinFET process at Intel. Compare to the older Core i3-7100U, the i3-7130U offers a 300 MHz improved clock speed.
The power consumption is rated at a TDP of 15 Watt and can be configured down to 7.5 Watt for thin and light designs (with a lower performance).
Intel Core i5-7440HQ► remove from comparison
The Intel Core i5-7440HQ is a quad-core processor for notebooks based on the Kaby Lake architecture and was announced in January 2017. Compared to the faster Core i7 models, the Core i5 does not support Hyper Threading and has lower clocks. The CPU cores run at 2.8 - 3.8 GHz (4 cores up to 3.4, 2 cores up to 3.6 GHz). The processor is also equipped with the HD Graphics 630 GPU as well as a dual-channel memory controller (DDR3L-1600/DDR4-2400). It is manufactured in a 14nm process with FinFET transistors.
Intel basically uses the same micro architecture compared to Skylake, so the per-MHz performance does not differ. The manufacturer only reworked the Speed Shift technology for faster dynamic adjustments of voltages and clocks, and the improved 14nm process allows much higher frequencies combined with better efficiency than before.
Due to the higher clock speeds, the performance of the i5-7440HQ is clearly faster than the old Core i5-6440HQ with 2.6 - 3.5 GHz. The performance is therefore sufficient even for demanding tasks.
The integrated Intel HD Graphics 630 has 24 Execution Units (similar to previous HD Graphics 530) running at 350 - 1000 MHz (i7 models up to 1100). The performance depends a lot on the memory configuration; it should be comparable to a dedicated Nvidia GeForce 920M in combination with fast DDR4-2133 dual-channel memory.
Contrary to Skylake, Kaby Lake now supports hardware decoding for H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The dual-core Kaby Lake processors, which were announced in January, should also support HDCP 2.2.
The chip is manufactured in an improved 14nm process with FinFET transistors, which improves the efficiency even further. Intel still specifies the TDP with 45 Watts, but it can also be reduced to 35 Watts by the notebook manufacturers (cTDP down). This will obviously affect the performance, because the Turbo Boost cannot be maintained for longer periods.
